Male sea lampreys may not be the best-looking creatures swimming in our lakes and streams, but they apparently have something going for them that the ladies may find irresistible.
Research by a team of Michigan State University scientists found that the males have a secondary sex characteristic that creates heat when they get near a female lamprey, something the females find hard to say no to. (more…)
When it comes to evolution, humans can learn a thing or two from primeval sea lampreys.
In the current issue of Nature Genetics, a team of scientists has presented an assembly of the sea lamprey genome – the first time the entire sequence has been decoded. The data is compelling as the sea lamprey is one of the few ancient, jawless species that has survived through the modern era.
The paper not only sheds light on how the venerable invasive species adapted and thrived, but it also provides many insights into the evolution of all vertebrates, species with backbones and spinal cords, which includes humans, said Weiming Li, Michigan State University fisheries and wildlife professor, who organized and coordinated the team.
